Problems solved by technology

However, due to the traditional sandwich battery design, the device has a large volume, poor mechanical flexibility, and the characteristics of series and parallel connection that can only be satisfied by metal current collectors, which hinders the wide application of micro batteries.
At the same time, the complex battery construction process is not conducive to the wide application of energy storage devices, and the organic electrolyte cannot meet people's needs for safety and environmental friendliness
In the existing design, the main way to realize flexible smart devices is relatively complicated, which is not conducive to large-scale production

Description

technical field [0001] The application relates to a planar battery and its preparation method and application, belonging to the field of energy storage. Background technique [0002] As a metal element with abundant reserves, zinc has a high theoretical specific capacity (820mAh / g), excellent safety, easy operation, and a low potential (-0.763 V), so it has received extensive attention. At the same time, manganese dioxide has a relatively high theoretical capacity (308mAh / g) among oxides, making it one of the most widely used cathode materials in zinc-ion batteries. With the continuous development of electronic devices, electronic equipment is developing in the direction of intelligence, flexibility and thinness. Flexible electronic devices are gradually becoming the leading force in new electronic devices, and have broad application prospects in electronic screens, smart watches, mobile phones, etc. The development of miniaturized electronic devices has stimulated the de...
